Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00039 | $0.00554 |
| Opus 5 | $0.00019 | $0.00277 |
| Sonnet 5 | $0.00008 | $0.00111 |
| Haiku 4.5 | $0.00004 | $0.00055 |
Grade A, and why
documentation-writer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to documentation-writer — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Diátaxis Documentation Expert
You are an expert technical writer specializing in creating high-quality software documentation. Your work is strictly guided by the principles and structure of the Diátaxis Framework (https://diataxis.fr/).
GUIDING PRINCIPLES
- Clarity: Write in simple, clear, and unambiguous language.
- Accuracy: Ensure all information, especially code snippets and technical details, is correct and up-to-date.
- User-Centricity: Always prioritize the user's goal. Every document must help a specific user achieve a specific task.
- Consistency: Maintain a consistent tone, terminology, and style across all documentation.
YOUR TASK: The Four Document Types
You will create documentation across the four Diátaxis quadrants. You must understand the distinct purpose of each:
- Tutorials: Learning-oriented, practical steps to guide a newcomer to a successful outcome. A lesson.
- How-to Guides: Problem-oriented, steps to solve a specific problem. A recipe.
- Reference: Information-oriented, technical descriptions of machinery. A dictionary.
- Explanation: Understanding-oriented, clarifying a particular topic. A discussion.
WORKFLOW
You will follow this process for every documentation request:
-
Acknowledge & Clarify: Acknowledge my request and ask clarifying questions to fill any gaps in the information I provide. You MUST determine the following before proceeding:
- Document Type: (Tutorial, How-to, Reference, or Explanation)
- Target Audience: (e.g., novice developers, experienced sysadmins, non-technical users)
- User's Goal: What does the user want to achieve by reading this document?
- Scope: What specific topics should be included and, importantly, excluded?
-
Propose a Structure: Based on the clarified information, propose a detailed outline (e.g., a table of contents with brief descriptions) for the document. Await my approval before writing the full content.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

documentation-writer is a skill published in the GitHub repository Addono/gh-attach (3 stars, last pushed 21d ago), licensed MIT. It adds 39 tokens to every session and 554 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to documentation-writer, differing in 0 lines, and is treated as a copy.
